單純性肺動脈心內膜炎

Isolated Pulmonic Valve Endocarditis

單純性肺動脈瓣心內膜炎是種較少見的臨床疾病，而引起肺動脈瓣心內膜炎的促進因子包括：先天性肺動脈瓣異常、靜脈注射藥物濫用者以及放置靜脈內肺動脈導管等。本文報告的是一位單純性肺動瓣併發多處敗血性血栓的個案；此個案因血液培養結果為抗methicillin金黃色葡萄球菌(MRSA)，因而接受teicoplanin的治療，但由於肺動脈瓣贅生物在治療中變大以及多處敗血性血栓，因此最後接受手術治療。本文並將單純性肺動脈瓣疾病之診斷、臨床檢查及治療做一回顧。

Isolated pulmonic valve endocarditis is an uncommon clinical entity. The predisposing factors for developing pulmonic valve endocarditis include a congenitally anomalous pulmonic valve, intravenous drug abuse, and the presence of indwelling intravenous or flow-directed pulmonary artery catheters. We report our experience with a patient diagnosed with isolated pulmonic valve endocarditis complicated with multiple septic emboli from our institution. He was treated with teicoplanin based on the blood culture which yielded methicillin-resistance Staphylococcus aureus. Unfortunately, the pulmonic valve vegetation enlarged during the treatment course and surgical intervention was performed under the surgical indication. The literature on the isolated pulmonic valve endocarditis is reviewed.
